Primary cutaneous anaplastic large-cell lymphoma (C-ALCL) is a rare entity of lymphoma. We report a case of C-ALCL presenting with hemophagocytic syndrome and skin lesion with giant ulcer. Histopathological examination of the skin biopsy specimens showed non-epidermotropic infiltrates with cohesive sheets of large tumor cells. The tumor cells showed CD4-, CD8+, CD30+, CD56-, ALK-, TIA-1+, and granzyme B+. C-ALCL is generally a disorder that progresses slowly and has a good prognosis. Manifestation of a giant ulcer and hemophagocytic syndrome, such as in the present case, is rare.

Development of Preliminary Criteria of Macrophage Activation Syndrome in Multisystem Inflammatory Syndrome Associated with COVID-19 in Children.

Macrophage activation syndrome (MAS) can be regarded as a key factor determining the severity of multisystem inflammatory syndrome associated with COVID-19 in children (MIS-C), and often requires treatment in the intensive care unit (ICU) to avoid life-threatening complications. No reputable specific criteria for the diagnosis of MAS in MIS-C patients have yet been identified, and criteria currently used for the diagnosis of hemophagocytic syndromes, such as HLH-2004, MAS-2005, and MAS-2016, are not sufficient for MAS in MIS-C. Our goal in this study was to work out the criteria for the early diagnosis of MAS in MIS-C.

Hemophagocytic lymphohistiocytosis (HLH) is a rare but potentially fatal entity characterized by an unregulated activation of the immune system. In the adult population, it is most commonly secondary to infectious, autoimmune, or neoplastic diseases. We present a case of a 23-year-old female diagnosed with infectious mononucleosis and hospitalized due to a persistent three-week fever and malaise with a new onset of jaundice and findings compatible with acute hepatitis and hepatosplenomegaly.

Although herpes simplex virus, Epstein-Barr virus, and hemophagocytic lymphohistiocytosis are known causes of severe acute liver injury with or without liver failure, these diseases occur almost exclusively in immunocompromised and elderly patients. We report a case of an immunocompetent young man with no medical history who presented with a subacute cough and persistent fevers in the setting of a penile chancre. He was found to have severely elevated liver chemistries and was subsequently diagnosed with hemophagocytic lymphohistiocytosis because of disseminated herpes simplex virus type 1 and Epstein-Barr virus coinfection.

Chediak-Higashi syndrome (CHS) is a rare multisystem genetic disorder of childhood, caused by a defect in vesicular trafficking, which is an essential process for intracellular transport. This defect results in the formation of giant cytoplasmic granules in various cell types, including white blood cells, melanosomes, and Schwann cells. The presence of giant lysosomal granules in neutrophils and their precursors is a distinct and diagnostic feature of CHS, differentiating it from other childhood immunodeficiency disorders, such as Griscelli syndrome and Hermansky-Pudlak syndrome, which share common characteristics like albinism and increased susceptibility to fatal hemophagocytic lymphohistiocytosis.

Background: The medico-surgical management of cardiac tumors when there is a suspicion of malignancy is complex. Moreover, in a critically ill setting, the choice of diagnostic tools seems crucial.
Case Presentation: We present the case of a sixty-four-year-old patient with no prior medical history who was admitted to the intensive care unit with obstructive shock secondary to a right heart mass and pulmonary embolism.
